recent crystal structures of CC chemokine receptors 2 and 9 (CCR2 and CCR9) have provided structural evidence for an allosteric, intracellular binding site. The high conservation of residues involved in this site suggests its presence in most chemokine receptors, including the close homologue CCR1. By using [3H]CCR2-RA-[R], a high-affinity, CCR2 intracellular ligand, we report an intracellular binding site
CC趋化因子受体2和9(CCR2和CCR9)的最新晶体结构为变构细胞内结合位点提供了结构证据。该位点涉及的残基高度保守,表明其存在于大多数趋化因子受体中,包括紧密同源的CCR1。通过使用[ 3 H] CCR2-RA- [ R ],一种高亲和力的CCR2细胞内配体,我们报道了CCR1的细胞内结合位点,其中该放射性配体也以高亲和力结合。此外,我们报告了一系列针对CCR1和CCR2的吡咯烷酮衍生物的合成和生物学特性,这使我们能够鉴定出几种高亲和力的细胞内配体,包括选择性和潜在的多靶点拮抗剂。评估功能性化合物中的所选化合物35 S]GTPγS分析表明,它们在CCR1中起反向激动剂的作用,提供了一种新的药理调节方式。因此,这种细胞内结合位点使得能够设计选择性和多靶点抑制剂作为一种新颖的治疗方法。
